Guerilla Philosophy: Is there room for philosophical graffiti?

The London Underground drivers are exposing commuters to philosophical thoughts ranging from Sartre to Gandhi (presumably over the speakers?). Here some philosophers and politicians share what aphorisms they would like to hear.

This made me think of what it would be like to do guerilla philosophy--graffiti with a philosophical twist, spread out across public spaces. Such graffiti is common in Latin America (Eduardo Galeano is good at collecting this "street wisdom." He has said: "The walls are the publishers of the poor".)


(Translation: Poverty is a time bomb)

Anyway, here is my selection for a philosophical nugget in the public sphere:

"With individuals, as with nations, respect for the rights of others means peace"

Benito Juarez
